In terms of perfect mechanics. Earl Strickland has many of the qualities to look for, so does Mika Immonen and Thorsten Hohmann.
How Bustamante comes up in a thread about perfect fundamentals, I have NO idea...
And BTW. Watching newer videos of SVB, has has tweaked his stroke, he now has a longer backswing pause and his break mechanics is simply amazing!
Earl was a major elbow dropper and his follow involved twisting his wrist.
